网络虚拟化被看作在分享的物理基础结构上部署不同网络体系结构和协议的一个强大的方法。嵌入的虚拟网络(VN ) 在网络虚拟化环境起一个重要作用。虚拟网络嵌入主要在附近高效地印射虚拟节点和虚拟连接到物理网络资源上。然而，负担平衡底层网络没收到许多考虑。这份报纸建议基于地位反馈印射算法的一个适应虚拟网络。主要贡献是根据底层网络的当前的负担分发嵌入虚拟网络请求。这个适应算法区分底层连接的剩余带宽并且充分利用多路径改进底层网络平衡的负担。当显著地减少平均底层连接压力时，模拟实验证明建议算法清楚地改进底层网络的负担分发。

英文摘要：

Network virtualization is considered as a powerful way to deploy different network architectures and protocols over a shared physical infrastructure. Virtual network （VN） embedding plays an important role in the network virtualization environment. Virtual network embedding is mainly about mapping virtual nodes and virtual links onto the physical network resources efficiently. However, load balancing of substrate network has not received much consideration. This paper proposes an adaptive virtual network mapping algorithm based on status feedback. The main contribution is to embed the virtual network requests according to the current load distribution of substrate network. This adaptive algorithm differentiates the residual bandwidth of substrate links and takes full advantage of the multi-path to improve the load balancing of the substrate network. Simulation experiments show that the proposed algorithm improves the load distribution of substrate network distinctly while reducing the average substrate link stress significantly.
